Abstract
The invention relates to a circular chassis of a drilling machine for a rock bolt on an electric transmission line. The circular chassis comprises guide rails and a bracket, wherein the guide rails are circular ring-shaped, the bracket is composed of two support beams arranged in parallel, a support rod is vertically arranged between the two support beams, a groove is formed in the lower surface of each support beam, and the shapes of the grooves are matched with that of the guide rails; a drill pipe support chassis is arranged above the bracket, and a drill pipe support is fixed on the chassis. The circular chassis is mainly applied to various small drilling machines for the rock bolt on the electric transmission line, is simple and convenient to produce and manufacture and relatively low in cost, and can guarantee that the construction time is saved and the small drilling machine is continuous, convenient and flexible for transportation and construction when the number of drill holes for a rock bolt foundation is larger.
Description
Technical field
The present invention relates to a kind of transmission line construction auxiliary equipment, relate in particular to a kind of transmission line of electricity rock bolt rig circular base plate, be mainly used in various transmission line of electricity rock bolt small-sized drill drilling constructions.
Background technology
Transmission line of electricity adopts Rock Bolt Foundation, and the corresponding environmental issue can save raw materials consumption, reduce construction costs, avoid heavy excavation, great explosion or digging foundation bringing has reached the object of engineering environmental protection, joint consumption, has important economy and social effect.Although rock bolt technology has research widely at home and abroad, more and more being applied on power transmission line iron tower foundation in recent years.But because domestic and international existing anchor bolt construction plant equipment is heavier, volume is large, be difficult to be applicable to mountain region transport and install, although therefore anchor rod foundation has good economic benefit and social benefit, be also difficult to promote on a large scale in transmission line of electricity always.Key is to lack the miniaturization rock bolt drilling equipment that can adapt to the complex-terrain environment such as mountain area; Small-sized drill drilling construction difficulty of the prior art, Rock Bolt Foundation drilling hole amount is more, when continuous drilling, small-sized drill construction adjustment bore position is dumb, the time long, difficulty is larger, especially in physical features cliffy mountain, when the construction of rock bolt small-sized drill continuous drilling, adjust bore position more difficult.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of transmission line of electricity rock bolt rig circular base plate is provided, solved Rock Bolt Foundation drilling hole amount more, when continuous drilling, the problem that bore position is dumb, the time long, difficulty is larger is adjusted in small-sized drill construction.
Technical scheme of the present invention is as follows:
Comprise guide rail and bracket, guide rail is annular, and bracket is made up of two brace summers that be arranged in parallel, between two brace summers, support bar is vertically set, and the soffit of brace summer is provided with groove, and groove shapes and guide rail match; The top of bracket arranges drill rod rack chassis, and drill rod rack is fixed on chassis.
Described guide rail external surface is arc-shaped convex.
Described guide rail below is provided with back-up block.
Described back-up block is 4 or 6 and arranges symmetrically.
Described guide rail radius is greater than near coal-mine radius.
Between described bracket and guide rail, be provided with fastening structure.
Described fastening structure is any in snap close, bolt jig or iron wire colligation.
Advantageous effect of the present invention is as follows:
1, adopted the cup dolly steel guide rail on round chassis, optional position continuous setup bore position in round chassis has been realized on the round chassis of drilling machine construction, easy to operate, flexible.
2, owing to having realized continuous setup bore position, when drilling hole amount is more, shorten the construction period, saved operating expenses;
3, round chassis cost is relatively low, convenient for production.

Detailed description of the invention
Embodiment
As Figure 1-5, comprise round ring guide 1 and bracket, round ring guide is arranged near coal-mine 7 outside, guide rail radius is greater than near coal-mine radius, and guide rail external surface is arc-shaped convex, and guide rail below is provided with 4 or 6 back-up blocks 8 of arranging symmetrically, bracket is made up of two brace summers that be arranged in parallel 2, between two brace summers, support bar 3 is vertically set, the soffit of brace summer is provided with groove 9, and groove shapes and guide rail arc-shaped convex match; The top of bracket arranges at the bottom of drill rod rack 4 and coils, and drill rod rack 5 is fixed on chassis.
Described fastening structure is any in snap close, bolt jig or iron wire colligation.
When transmission line of electricity rock bolt small-sized drill is constructed on the rock of mountain area, round ring guide be laid on Rock Bolt Foundation near coal-mine on, rotating bracket is laid on cup dolly steel guide rail, and the groove of rotating bracket is stuck on circular guideway and also fixes by modes such as snap close, bolt jig or iron wire colligations.Bored after a rock pore, opened snap close, bolt jig or iron wire colligation, bracket moves along guide rail on guide rail, and bracket is fixed in round ring guide arbitrfary point, and fixing borer drill rod support is realized the base of need not rigging down continuously and carried out continuous drilling construction.
Through twice true type test, 3 test specimens are tested altogether.Compare with other small-sized drill bracket, can shorten rig and creep into the duration 48%, reduce investment outlay 19 ~ 22%.
